Web service Axis2 client code generation issue

Question

I'm trying the consume a web services built using Axis2, so I have followed this example for creating client code.

I have the endpoint and I'm able to access it through the browser. But trying to generate the client code with:

WSDL2Java.bat -uri <<endpoint>> -o client

throws the exception below:

Exception in thread "main" org.apache.axis2.wsdl.codegen.CodeGenerationException: Error parsing WSDL at org.apache.axis2.wsdl.codegen.CodeGenerationEngine.(CodeGenerationEngine.java:181) at org.apache.axis2.wsdl.WSDL2Code.main(WSDL2Code.java:35) at org.apache.axis2.wsdl.WSDL2Java.main(WSDL2Java.java:24) Caused by: java.net.ConnectException: Connection timed out: connect at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:351) at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:213) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:200) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:366) at java.net.Socket.connect(Socket.java:529) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.connect(SSLSocketImpl.java:570) at com.sun.net.ssl.internal.ssl.BaseSSLSocketImpl.connect(BaseSSLSocketImpl.java:141) at sun.net.NetworkClient.doConnect(NetworkClient.java:163) at sun.net.www.http.HttpClient.openServer(HttpClient.java:411) at sun.net.www.http.HttpClient.openServer(HttpClient.java:525) at sun.net.www.protocol.https.HttpsClient.(HttpsClient.java:272) at sun.net.www.protocol.https.HttpsClient.New(HttpsClient.java:329) at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.getNewHttpClient(AbstractDelegateHttpsURLConnection.java:172) at sun.net.www.protocol.http.HttpURLConnection.plainConnect(HttpURLConnection.java:923) at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(AbstractDelegateHttpsURLConnection.java:158) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1195) at java.net.HttpURLConnection.getResponseCode(HttpURLConnection.java:379) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getResponseCode(HttpsURLConnectionImpl.java:318) at org.apache.axis2.wsdl.codegen.CodeGenerationEngine.(CodeGenerationEngine.java:99) ... 2 more

What could be the reason for this error?

Answer 1

If you can access the WSDL from a browser but not from the tool in command line then it's possible that your browser uses a HTTP proxy for it's connection while wsdl2java goes straight for the address.

Try setting some JVM parameters for using a proxy, as described in Java Networking and Proxies and if that fails, there is always the option to download the WSDL with the browser and run wsdl2java with the locally downloaded file.
